Cary Institute of Ecosystem Studies, Environmental Monitoring Program, Low-Volume Filter Pack Air Chemistry Data

Cary Institute Of Ecosystem Studies & Vicky Kelly
The Cary Institute Environmental Monitoring Program is a long-term program to monitor environmental parameters that are important to natural ecosystems. The program includes monitoring of air, precipitation and stream chemistry as well as meteorological, solar radiation and physical stream parameters. The Cary Institute also hosts sites for two additional programs: The New York State Department of Environmental Conservation Ambient Air Monitoring Program, for ground level ozone and the National Oceanic and Atmospheric Administration (NOAA), U.S....

Zostera Epifauna 1975-1979 Beaufort NC

North Carolina NC State & Harvey Stuart
I took samples of plants and animals discontinuously (1975-1979) in two sites at Drum Shoals (34o 42�40�N, 76o 46�20�W) in Bogue Sound and two sites at Middle Marsh (34o 41�32�N,76o 37�20W) in Back Sound. Both are sites of eelgrass (Zostera marina) beds located in Carteret County, NC, USA. Drum Shoals is located at least 250 m from the nearest Spartina marsh whereas Middle Marsh sites are located from 10 to 80 m from the nearest...

Extracellular enzyme activities in the Maumee and Ottawa Rivers (OH) from 1994 to 1995

Duke University Biology Department & Robert Sinsabaugh
The data include estimates of bacterial production and apparent Vmax (a measure of catalytic capacity) and apparent Km (a measure of available substrate concentration) for six extracellular enzymes (alpha-glucosidase, beta-glucosidase, aminopeptidase, protease, phosphatase, acetyl esterase) measured in the Maumee and Ottawa Rivers of Ohio (USA). The purpose of the dataset was to integrate the effects of temperature and resource availability on bacterial production using metabolic scaling theory and the kinetics of EEA.

Data and analyses for Hooper et al. (2012) Nature, �A global synthesis reveals biodiversity loss as a major driver of ecosystem change�, DOI: 10.1038/nature11118.

NCEAS 12560: Cardinale: Biodiversity And The Functioning Of Ecosystems: Translating Results From Model Experiments Into Functional Reality, National Center For Ecological Analysis And Synthesis & Dave Hooper
Many experiments have shown that species loss can alter key processes important to the productivity and sustainability of Earth�s ecosystems. However, it is unclear how these effects compare to the direct effects of other forms of environmental change that are both driving diversity loss and altering ecosystem function. We used a suite of meta-analyses of published data to show that the impacts of species loss on productivity and decomposition - two processes important in all...

GeoSymbio: Symbiodinium-host symbioses

NCEAS 12595: Edmunds: Tropical Coral Reefs Of The Future: Modeling Ecological Outcomes From The Analyses Of Current And Historical Trends, National Center For Ecological Analysis And Synthesis & Erik Franklin
A global Symbiodinium data set using genetic, taxonomic, collection event, and reference information of DNA sequences of the Internal Transcribed Spacer-2 (ITS2) region of the nuclear ribosomal array. This data corresponds to the supplemental information from Franklin EC, Stat M, Pochon X, Putnam H, Gates RD. 2011. GeoSymbio: a hybrid, cloud-based web application of global geospatial bioinformatics and ecoinformatics for Symbiodinium-host symbioses. Molecular Ecology Resources. DOI: 10.1111/j.1755-0998.2011.03081.x

Individual-based food web (Guadalquivir estuary, southern Spain)

Instituto De Ciencias Marinas De Andalucia & Pilar Drake
Stomach contents and estimates of abundance were collected monthly from February 1998 to January 1999 at three locations in the estuary of the Guadalquivir river, southern Spain. Samples were taken across a range of different environmental conditions, with seasonal variations in temperature and spatial variations in salinity.

Gill net survey of fishes of Oneida Lake, NY, 1957 - 2010

Lars Rudstam & James R. Jackson
The Cornell Biological Field Station (CBFS) serves as a primary field site for aquatic research at Cornell University (more information can be found at http://www.dnr.cornell.edu/fieldst/cbfs.htm) and is part of the Department of Natural Resources, College of Agriculture and Life Sciences. The centerpiece of the station's research program is a 50-year database on the food web of Oneida Lake, New York, that has been collected with support from the Cornell University Brown Endowment and from the...

Multi-decade population studies of Michigan old-growth forests

NCEAS 12218: Woods: Slow Systems And Complex Data-Sets: Multi-Decade Permanent Plots Permit Address Of Recalcitrant Questions About Late-Successional Forests, National Center For Ecological Analysis And Synthesis & Kerry Woods
Established in 1935, a regular grid of 256 permanent plots includes about 20% of a 100-ha old-growth forest at the Dukes Research Natural Area in northern Michigan, USA. Woody stems have been remeasured 3�7 times providing extensive quantitative records of population and community dynamics over periods of up to 72 years. Woody stems in upland hemlock�northern hardwood stands, about half of the study plots, have been mapped and individually tracked since about 1990. Remaining plots...

Global change, global trade, and the next wave of plant invasions: Data

NCEAS 12622: Sorte: Climate Change And Invasive Species: Are Non-Natives Poised For Greater Success In Future Climatic Conditions?, National Center For Ecological Analysis And Synthesis & Bethany Bradley
Data presented here are those used for the following publication: Bradley et al. 2011. Global change, global trade, and the next wave of plant invasions. Front Ecol Environ 10(1): 20-28. doi: 10.1890/110145 Data from the USDA's global agricultural trade system online database were used to identify emerging (those with an average import value of less than $100,000 from 2000-2010) and established (those with an average import value of more than $100,000 from 2000-2010) sources of...
